b26d28d964 This patch implements optimized objectInfo structure which manages the set of observers associated with an object and the changeRecord types which they accept.
Observation in the normal case (Object.observe, default accept types, one observer) now allocates fewer objects and unobservation no longer needs to scan and splice an InternalArray -- making the combined speed of observe/unobserve about 200% faster.

This patch implements the following optimizations:

-objectInfo is initially created without any connected objects or arrays. The first observer is referenced directly by objectInfo, and when a second observer is added, changeObservers converts to a mapping of callbackPriority->observer, which allows for constant time registration/de-registration.

-observer.accept and objectInfo.performing are conceptually the same data-structure. This is now directly represented as an abstract "TypeMap" which can later be optimized to be a smi in common cases, (e.g:   https://codereview.chromium.org/19269007/).

-objectInfo observers are only represented by an object with an accept typeMap if the set of accept types is non-default

35490d82a9 Add OptimizedCodeList and DeoptimizedCodeList to native contexts. Both lists are weak. This makes it possible to find optimized code that is not referred to by any function, but still needs to be deoptimized. It obsoletes the weak deoptimizing code list in the deoptimizer data and generally simplifies the process of deoptimizing code.

281de965a4 Import ConditionVariable class.
Condition variables are synchronization primitives that can be used
to block one or more threads while waiting for condition to become
true.

Right now we have only semaphores, mutexes and atomic operations for
synchronization, which results in quite complex solutions where an
implementation using condition variables and mutexes would be straight
forward.

There's also a performance benefit to condition variables and mutexes
vs semaphores, especially on Windows, where semaphores are kernel
objects, while mutexes are implemented as fast critical sections,
it CAN be beneficial performance-wise to use condition variables
instead of semaphores.
